WILLIAM HAWKS, OF DULUTH, MINNESOTA, ASSIGNOR OFcONE-HALIE TO CHAR'LESW. V

ANDREWS, OF.DUL'UTH, MINNESOTA.

Toall whom, it may concern:

Be it known that I, WILLIAM HAWKS, citizenofthe United States, residing at Duluth, in the county of St. Louis and State of -Minnesota, have invented certain new and useful'lfmprovements in WVaterHeating Apparatus, of which the following is a specification.

, This invention relates to improvements in water heating apparatus more particularly adapted for use with domestic standboilers, and theprimary object of the invention is to provide an improved form of heater in which the water will enter at a point lower thanthe discharge outlet to induce circulation.

A. further object is to provide improved means for arresting and deflecting the heat against the heater, and means for adjustseveral parts hereinafter more fully ,de-'

scribed and claimed and shown in the accompanying drawings illustrating the 'embodiment of the invention, andin which Figurel is a longitudinal sectional view of an lmproved device of th1s character conp structed in accordance with the principles of this invention. Fig. 2' is a detail sectional view on line 22 of Fig.1. Fig. 3 is an enlarged detail sectional View on line 3---3 of Fig. 4. Fig. 4 is a top plan view of the burner. Fig. 5 is an enlarged detail see tional view slmilar, to F g. 1 of a modrfied arrangement of the heater.

Referrlng more partlcularly tothe'drawings and in the present. exemplification off the invention, the numeral 10 designates the ordinary stand boiler, which is provided with a supply inlet 11, connected to which isa tubular member 12 which extends into the boiler at ai point adjacent the bottom thereof, and 13 designates the outlet openving at the top of the boiler for conducting cation with a heater designated generally by the reference numeral 16 in Figs. 1 and 5.- This heater 16 may be constructed in any an upward direction and out WATER-HEATING APPARATUS.

desired or suitable manner but is preferably 1 cast and 1s hollow reform a circumferentlal chamber 17 which has communication with a chamber 18,which is preferably located at thecenter of the heater by an upwardly inclined passage 19. A portion of the botto have communication'with the chamber 18. A tubular member 22 is also provided to form a communication between the boiler 10 through the bottom 14 thereof at a point remote from the tubular -member 15, and

this tubular member 22 extends into, the

heater l6through the top thereof andinto the depressed portion or chamber 20. The bottom of this depressed portion 20 is located at a point below the inlet'end of the passage 19 and the extremity of the tubular member 22 which projects into the depressed portionjorchamber'20 terminates atv a point below the bottom of the inlet or the passage 19, so that the waterfrom the boiler 10" will be discharged into the heater 16 through the tubular member 22, and into the depressed'portion' or chamber 20 so-as to the water to circulate through the heater in" through the tubular'member 15.} p i I Arranged within the boiler 10 is a pipe or tubular member 23 which has communicationwith the tubular member 15 and extends to a point adjacent the top of the boiler so that the heated water entering the tubular member 23 will be'conveyed to a point above the point, at which the cold water enters the boiler through the tubular member 12.

The heater 16 is supportedjby means of a stand 2 1 which is provided with a base 25,

and this stand 24: is secured to the heater 16 in any desired or suit-able manner, preferably by means of the threaded extremity 26 thereof engaging in a suitablethreaded aperturein a reinforced portion 27 at the the heater is thus supported the boiler 10 will in turn be supported by the heater through the medium of the tubular .mem-s,

ber 15.

A shell orjacket 27 surrounds the boiler and is spaced therefrom. This shell or jacket is provided with an open lower extremity and depends below the bottom of the boiler 10 so as to surround the heater 16 and to project below the heater. The

- shell or jacket may be supported and held r adjustably supported on the stand 24 so as preferably converted and is provided with tobe moved toward or away from the heater 16 and into and out of the lower-extremity of the shell or jacket 27 A suitable fastening device 32 such as a screw or its adj usted position. V

The burner 31 preferably comprises a bottom ring-shaped member 32 which'is of a channel formation, the outer' flange 32*" of which is preferably inclined outwardly, and an upper ring-shaped member 133 which is bolt, is provided for securing the burner in a plurality of notches or open recesses 34 arranged around the, periphery thereof.-

This member 33 ofthe burner is also pros vided with. a depending flange 35 which is adapted to surround the inner flange 32* of the bottom member 32 and'to rest upon the member 32 between the flanges when placed in position so that thenotches or recesses 34 will stand adjacent the upper edge-of the outer flange 32. The flange 35 of the member 33 is slightly spaced from the flange 32 of the member 32 and is held spaced therefrom by means of a plurality of lugs 36 which project beyondthevflange 35and engage the adjacent face of the flange 32*, as shown more clearly in Fig; 4 of the drawings. The notches or recesses 34 are so disposed that the flame therefrom will strike or impin'g'ethe depending flange or heat deflector 21 of the heater 16, which latter will direct the flame against the'bottom of the heaters By providing the lugs 36 on the member33, a circumferential space 37 will be formed around the inner periphery of the burner, which space "may be of any desired width but is preferably a narrow space, through which gas" will pass to be ignited and burned around the inner edge of the ring. The purpose of this space and the supplemental flame isIto form a tight jointto prevent the escape of gasand thereby obviates the necessity of constructing a burner having fluid tightjoints where the parts join. With this construction,- the burner may be constructed of two coiipe'rat" ing members, one of which removably rests upon the other member so that when it 1s desired to clean the burner, all that'is necessary after the flame has been extinguished is to release the fastening device 32 and lower theburner 31 on the stand 24 away from the heater 16 to a convenient point for i zle 39 of the supply pipe '38, all that is necessary after releasing the fastening device 32 is 'toraise' the burner slightly on the stand 24,- after which it may be axially rotated to mov'e'the tubular extension out of line with the nozzle 39 after which the burner may be readily lowered.

The heater 16 is provided with openings 41 between the circumferential chamber 17 and the chamber 18, and which openings are located below the bottom of the boiler 14 so that the products of combustion from the burner will pass through the openings and impinge upon the bottom 14 of the boiler; at the same time; the products will escape into the space between the boilerand the shell or acket 2?, which latter may be provided with a vent opening 42 at the top thereof for the escape of the products.

7 The heater 16 is providedwith an upwardly projecting circumferential flange 43 extending above the top thereof to form a receptacle to catch the products of condensation which may be formed upon the surface of the boiler. The heater may also be provided with openings 44 which extend through the periphery thereof, preferably through thelugs 29, and said openings have communication with the chamber 17 so that when itis desired, an inlet pipe 45 which leads from the waterback of the furnace may be connected to one of the openings'to have communication with the chamber-*'17,"

back may be connected to the other opening 44 so that in the event that the water-back of a furnace is attached to a heater, the water entering the'hea'ter 16 through the tubular member. 22 will pass out of the heater through the pipe 46 and, into the waterback. From the water-back it will pass and the outlet pipe'46 leading to the waterg through the pipe 45 to be discharged into the heater 16 to flow through the'passage 19,

15, ipe 23,

chamber 18, tubular member and back into the boiler.

When it is not desired to use the waterback, the pipes 45 and 46 may be detached from the heater 16 and suitable plugs 47' may be inserted in the openings 44 to close the same, the shell or jacket'27 being pro vided with apertures registering with the openings 44 to permit theattachment of the pipes or plugs 47. v

NVith this improved construction it will be apparent that by providing, the depending flange 21 on the heater, the flame from the burner will be gathered in'such a manner as to deflect the same toward the center {of the heater and through the openings 41 against the bottom of the boiler. It will also be apparent that by providing the catch basin or receptacle at the top of the heater for the water of condensation which forms. when the boiler is first heated, the water will ing an annular water chamber and an outlet.

chamber encompassed by the annular chamber, the bottom of the second recited chamber being located in a plane above the bottom of the annular chamber, an inlet passage for the inner chamber leading from the annular chamber and inclining upwardly therefrom, anoutlet for the inner chamber leading through the top thereof and an inlet opening for the annular chamber, the bottom of the latter chamber adjacent the inlet opening being depressed. v

2. Awater heater comprising a body having an annular water chamber and an outlet chamber encompassed by theannular cham-i her, the bottom of the second recited chamber being located in a plane above the bottom of the annular chamber, an inlet passage for the inner chamber leading from the annular chamber and inclining upwardly there from, an outlet for the inner chamber leading through the top thereof and an inlet opening for'the annular chamber, the bottom of the latter chamber adjacent the inlet opening being depressed, said chambers being spacedcfr'om; each other to form a heatpassage therebetween'.

3. A water heatercornprising a-body having an annular water chamber and an outlet 7 chamber-encompassed by the annular chamher, the bottom of the second recited chamber being located in a plane above the bottom of the annular chamber, an inlet passage for the inner chamber leadin from the an- "nular. chamber and inclin ng upwardlyv therefrom, an outlet for the inner chamber leading through the top thereof and an inlet opening for the annular chamber, the bottom of the latter chamber adjacent the inlet '.--ap'ening being depressed, said chambers being spaced from each other to form a heat passage therebetween, and said heater being provided with integral wall at the top thereof to form an upwardly opening receptacle for the water of condensation.

4. A water heater comprising a body having an annular water chamber and an outlet chamber encompassed by the annular chamher, the bottomof the second recited chamber being located in a plane above the bottom of the annular chamber, an inlet passage for the inner chamber leading from the annular chamber and inclining upwardly therefrom, an outlet for the innerchamber leading through the top thereof and an inlet opening for the annular chamber, the bottom of the latter chamber adjacentthe inlet opening being depressed, said chambers being spaced from each other to form a heat passage therebetween, the outer chamber being provided with an integral dependingannular flange encompassing the inlet to the said heat passage. 7
